Re: [Pharo-dev] Scroll bug since ever. Someone?

by Camillo Bruni

that happens only on the trackpad if you scroll diagonally ;) Or well, when you scroll vertically and you are not fully vertical, from time to time you get a horizontal scroll even from the VM which arrives as a keypressed at VM side. Usually some ctrl+shift+arrow combo, which makes your list jump to the location you previously selected: https://pharo.fogbugz.com/f/cases/5296/Fast-Scroll-Down-produces-weird-even… I think the only proper solution is to have proper scroll events, and to not emulate them with key combinations.

Scroll bug since ever. Someone?

by Mariano Martinez Peck

Hi guys. We have a bug with the scrolling since I can remember.... You know...when you scroll down fast, at some point it restarts the scroll in a higher position, making it impossible to really scroll down. If you scroll down slower, it works. I guess I am not the only one seeing this problem right? Tomorrow we have a sprint here in Argentina. Would I be loosing my hours trying to find this bug? Because as said, I think it's been here since ever.... Any point? Thanks, -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-dev] Nautilus groups in 3.0

by Esteban Lorenzano

if it is there, someone re-added it (because I removed it). anyway, just to be clear: 1) the three is not going to go... is there to stay. We can (and should) improve it, but we are not going to remove it. 2) what we can do is to re-add the "groups" button and a preference to join or not-join groups in the three panel. So, sorry for the hate, but you better deal with it :) On Wed, Nov 6, 2013 at 11:11 AM, Torsten Bergmann <astares(a)gmx.de> wrote: > >is not on top, "groups" are removed (since now they are on top, no need > for a button). > > But thats what I mean - the "Groups" button is still there.

It's more complicated than it might seem. (As in, two hours later I'd fixed a few issues, but had nothing running.) frank > Bye > T. >

[OT] Booting on top of JS in webbrowser

by Torsten Bergmann

While in the past we had OS-platforms where Smalltalk provided VM solutions. Then there was/is .NET and Java as platform. Nowedays the browser becomes the next platform with bootable stuff directly on top of JavaScript. http://bellard.org/jslinux/ http://copy.sh/v24/ (Try to boot visual Colibri OS) http://vps2.etotheipiplusone.com:30176/redmine/projects/emscripten-qt/wiki/… CogVM with Pharo or SqueakNOS on top of JavaScript anyone ;) Bye T.

See if you can prime them by getting them to first play the game Kodable on the iPad, before they get there. Then you'll have more impact. I have my young kids playing it and its worth trying it out yourself. cheers -ben

>is not on top, "groups" are removed (since now they are on top, no need for a button).Â Â But thats what I mean - the "Groups" button is still there. Directly behind the "Hierarchy" button (but visible by a few pixels on the left). Just have a look (see attachement). Use the morphic halos to move the button morph and you will see him. Is this a "easter egg" or is your "group" cleanup not yet finished? Thx T.

Yes, there is also a notes rewrite if rebase or amend :( I'll go to the sprint on 19/12; maybe we can look into what we have on that: new format / metadata / EPICEA-readiness.
